Calculating Strain in Wood Compression for Plotting Stress

Click For Summary
SUMMARY

The discussion focuses on calculating wood strain in compression to plot against stress using the formula for strain: ΔLength/Initial Length. Participants confirm that to obtain strain values, one must divide each extension measurement by the initial length of the wood specimen. This method allows for accurate plotting of strain from zero load to failure, facilitating a comprehensive analysis of wood behavior under compression.

PREREQUISITES
  • Understanding of basic mechanical properties of materials
  • Familiarity with strain and stress concepts
  • Knowledge of wood properties and behavior under load
  • Ability to perform calculations involving ratios and percentages
NEXT STEPS
  • Research the effects of different wood species on strain and stress behavior
  • Learn about stress-strain curves specific to wood materials
  • Explore software tools for plotting stress-strain relationships
  • Investigate advanced methods for measuring wood deformation under load
USEFUL FOR

Wood scientists, structural engineers, materials researchers, and anyone involved in the study of wood mechanics and performance under compression.

How can I calculated the wood strain in compression to plot it with stress, if the data that I have is the length and several extension data. The extension data corresponds since the 0 load to the the failure. Thanks.

Since the equation for Strain is: ΔLength/Initial Length

In order to make a plot of strain Should I calculate the strain at each point by dividing each extension over the Initial Length?

Thanks

Thread 'Hydraulic Cylinder Held In Place Until Needed'

I have encountered a vertically oriented hydraulic cylinder that is designed to actuate and slice heavy cabling into sections with a blade. The cylinder is quite small (around 1.5 inches in diameter) and has an equally small stroke. The cylinder is single acting (i.e. it is pressurized from the bottom, and vented to atmosphere with a spring return, roughly 200lbs of force on the spring). The system operates at roughly 2500 psi. Interestingly, the cylinder has a pin that passes through its...
